TROLLEY-STAND.

SPECIFICATION forming part of Letters Patent No. 618,231, dated January24, 1899.

Application filed April 121 1898. Serial No. 677,349. (No model.)

To all whom it may concern:

Be it known that I, DANIEL MoYnR, a citizen of the United States,residing at Allentown, in the county of Lehigh, State of Pennsylvania,have invented certain new and useful Improvements in Trolley-Stands, ofwhich the following is a specification, reference being had therein tothe accompanying drawings.

This invention relates to trolley-stands, and is particularly adaptedfor use in connection with the trolley-pole used to establish electriccontact with an overhead conductor supplying current for an electricrailway.

The invention has for its object to provide an improved construction bywhich the stand may be completely reversed and in which independentmeans are used to produce the necessary tension upon the trolley-pole.

The invention has for a further object to relieve the tension devicesfrom all strain when the pole is in a vertical position and to bringinto operation only one set of tension devices when the pole is in use,whereby in the event of a breakage of the parts the pole may be reversedand the opposite set of tension devices brought into operation.

A further object is to provide a construction by which the pole may bedepressed into a substantially horizontal position in order to passbeneath a low bridge or car-barn door.

Other objects and advantages of the invention will hereinafter appear inthe following description, and the novel features thereof will beparticularly pointed out in the appended claims.

In the drawings, Figure 1 is a side elevation of the trolleystand. Fig.2 is an end elevation of the same. Fig. 3 is a detail perspective of thelevers carried by the pole-socket, and Fig. 4.- is a detail horizontalsection showing the means for securing the pivoted frame upon the postcarried by the ear-roof.

Like letters of reference indicate like parts throughout the severalfigures of the drawings.

The letter A designates a base secured to the roof or other portion of acar in any suit his post is provided adgroove A and forms a pivotalsupport for the block B, which carries the oppositely-extendingsupporting=frames B. These frames are secured to the block 13 by anysuitable means'for instance, bolts B -and the opposite ends of theframes B are provided with sockets B The block B is pivotally mountedupon the post A and secured against vertical movement thereon by anysuitable means passing through the block and the groove A in the postA-for instance, a split pin a. The trolley-pole socket O is pivoted inthe upper portion of said block B by any suitable means-for instance, bya pivot-pin 0 passing through the block and extending beyond theopposite ends of the socket. The lower portion of this socket isprovided with forked extensions constituting levers 0 said levers beingprovided with lateral extensions 0 at their lower ends, from which pinsor lugs C extend inwardly at one end, and similar pins or lugs C extendoutwardly at the opposite end. The levers O are provided withpivoting-apertures O for the reception of the pivotbolt C, and the upperend of the socket is adapted to receive the trolley-pole G which issecured in position by any usual means for instance, set-screws 0 Uponthe pivot-bolt 0, between the post B and levers 0 there are locatedopposite tension-arms D, while beyond the outer face of the levers C asimilar set of opposite tensionarms D are provided. The lower ends ofthese arms are connected with any suitable tension devices-for instance,a spring E which may be connected to the arms by means of an interposedlink E and to the frame 13 by means of an adjusting-bolt E passingthrough the sockets B and adapted to be adjusted by means of a nut Ebearing against the outer face of said sockets. Similar springs areconnected to each of the arms, and each set of springs is connected to across-bar E ,which is removably attached to the adjusting-bolt E bymeans of a bolt 6. The springs E are connected to the inner set of armsDand are attached to the cross-bar E at one end of the stand-forinstance, the left end, as shown in Figs. 1 and 2and the battery oftensionsprings connected to the opposite outer arms D are connected tothe cross-bar E and adjusted by the bolt E at the right end of themachine. It will be observed that when the pole is in a verticalposition, as shown in Fig. 1, the springs are relieved from all tension,save that of their adjusting-bolts, while as soon as the pole isdepressed for engagement with the trolley-wirefor instance, toward theright of Fig. 1the pins or lugs 0 upon the opposite levers C will engagethe opposite outer tension-arms D and bring the trolley pole under thetension of the springs at the right end of the stand. lVhen it isdesired to depress the pole to more than the normal extent, the spring Ewill yield and permit such depression until the pole is in asubstantially horizontal position. The tension of the springs will beregulated and adj usted by means of the nuts E so as to exercise thedesired pressure upon the trolleypole. lVhen it is desired to reversethe trolley-pole either at the end of a trip or by reason of injury tothe springs or tension-arms, it is simply necessary to swing the frameupon its pivotal support to bring the opposite battery of springsconnected to the arms D into the position previously occupied by theother end of the stand. This reversal is not necessary in the ordinaryuse of the stand, as it will be seen that the socket can be depressed ineither direction, and if depressed toward the left the arms D willengage the pins 0 and act in the manner just described in connectionwith the arms D. A trolley-stand is thus provided which guards againstall delay incident to a breakage of the tension devices and which iscapable of use without the necessity of reversing the stand when thedirection of incline of the trolley-pole is changed. The use of theindependent springs for governing the tension upon the pole obviates allthe disadvantages occasioned by the breakage of the single spring usedin a number of previous constructions.

It is obvious that numerous changes may be made in the details ofconstruction without departing from the spirit of the invention, asdefined by the appended claims.
